I installed some Depo P90 v2 head lights on my car, and ever since get an error when I turn on/off my car. I looked it up in the manual and it says it's just a general head light problem. Not low beams or high beams. I was gonna try to code for the cold weather/warm weather checks but couldn't manage to find the code in my ECU. Is this because I don't have xenon lights? Do halogens not do the cold weather/warm weather checks? Also, I was wondering if maybe coding my car to think it would have xenons would help.

Any help/guidance would be great. I hate getting that error whenever I turn on the car.

Here's a pic of the error I get. I looked it up in the manual and it's not very specific. It basically says something is wrong with the headlights.

In the BMW CODING success thread there is a spreadsheet with a bunch of info. They have a bunch of codes for "Bulb Test Warning". Those are the cold weather/warm weather bulb tests that I was referring to. I don't have the files on this computer I'm using right now to show you my .MAN file, but after doing multiple searches for various function values (ie. WARMUEBERWACHUNG_AL_L etc.) I can't find any.

Also, just to clarify this error was not caused by coding. It has been an issue ever since I installed my Depo P90 version 2 head lights. I had just hoped that I would be able to fix the error via coding.

You can, you code out the bulb check system...it's explained in the sheet that's in the original post of that huge coding thread.

Btw, it's not cold and warm "weather". It's cold, for start up. And warm for when the bulbs have been on for a period of time.

Which module are you going into?

So you're saying I need to code for all the bulb test warnings? I was gonna try that, but when I was looking through the FRM module I couldn't find any of the code. I have a 2006 325i. Is there any way that code is in a different module?

Thanks guys. I must have been looking through a different module when I was searching for the code functions. I'm guessing that it's my turn signals that are throwing the error since they're LED in the Depo P90 v2.

When I get some time I'll try it again and post back if it all works out.

Okay, so I had a chance to mess around with it for a bit. First I coded pretty much everything I could find with KALTUEBERWACHUNG and WARMUEBERWACHUNG in it. The reason I did this instead of just looking for the specific ones is because the functions in my FRM module don't match up exactly with what is in the spreadsheet. This didn't fix the issue. I was still getting the error, so I messed around a bit more and thought I'd code for the angel eyes error that is found just above the bulb test warnings in the spreadsheet. I went to Google Translate and found out FEHLMERELDUNG means ERROR MESSAGE in English so I coded everything with FEHLMERELDUNG to not active.

Good new is the error is gone. I'm not sure how important it is that I go back and test each one, one by one to see which one it is that is causing the error. Should I go back and change all the bulb test warnings to active or am I okay just leaving them off? And what about the ERROR MESSAGES that I disabled?

I'm just glad to finally get rid of that error message every time I started the car. It drove me crazy.

I just went through and matched up my bulb test warning functions with my backup and read it to my FRM module in my car. After they were all changed back, I'm still not getting the error. It must have been one of the FEHLMERELDUNG functions I changed. If I isolate exactly which one it is, I'll let you guys know.

Here's a list of the FEHLERMELDUNG functions that I coded. One (or a combination of) these got rid of my errors. I'm guessing that the L and R in the function stand for left and right, but I don't know what anything else stands for. If you guys know, it would help me out a lot in determining which one of these solves my problem, and which ones I need to change back.

That error is not from your low beam or high beam lights (it is a different symbol). It could be your turn signal, AE, sideblinkers, rear lights, license plate lights etc.

You have to find out which bulb is throwing that error and then disable the warm/cold start checks.

Yup. I have the same exact error light and although I know exactly why I'm receiving that, you can push and hold the BC (Board Computer) button for a around ~5 secs and it should give you a CC-ID number. Mine was CC-ID 371 meaning it was my license plate lights. PM for the list of CC-IDs
